When the strip has suflicient-ly advanced,

the previously mentioned complete rotation of the holder and plunger,togeth'erwrth the box blank projecting beyond finge'rs12, will takeplace. During thisrotatiomthe strip is wound around the box, against.

which it is pressed by the Weighted lever 22,'such lever permitting theroller lty its play to follow the contour of the box.

After a complete rotation of the blank has taken place, it will beintermittently arrested.owing to mutilated wheel 21. Cam 14 will noweffect a further advance of plunger 19 together with the blank, and,

carry the latter to means for folding projecting portions of strip 24.These means consist of a laterally movable slide 29 carrying a number offolding levers 30, {31, (Figs. 6 and 7), which are connected in pairs byrods 32, 33. The levers are so actuated by springs 34, 35, and by aneccentric55 of shaft36, that they will be projected over the box bottom"and will quickly rocede now tekes'place so that the blank is pushedinto. matrix 39 of slide 29, thebottom of which constitutes a fixedslide guide 40. Piston 19 now quickly recedes, and then a second advanceof levers 30, 31 through 'a nose 38 of disk 55 takes place, whereby theportions of strip 24 that project beyond the front edge of the box'areturned toward the same (Fig. 8). Slide 2%) will now be moved sidcwisetogether with matrix 39, by crank arm 41 and shaft 42 which is rockedfrom cam 43 by cam lever 45 and crank 44. By the lateral movement ofslide 29, the blank is presented to a second plunger 46 which isadvanced from ca1n'48 against action. of. spring 50. Plunger 46 issecured to a rigid plate 47 by an interposed resilient member 49 formedof rubber or similar material, .the exposed rim of member 49 beingnorm-ally flush with the rims of -plunger 46 and plate 47, as clearlyillustrated in Fig. 8. lVhen the plunger is projected into the box, itwill engage the in wa'rdly turned portion of strip 24 and fold itagainst the inner faces of the box sides. When the rigid head 46 of theplunger is pressed against the bottom of the matrix, the resilientmember 49 will be swelled outces upw'ard,' the severed slips willibe atonce secured at ward, so that the folded strip is forced tightly againstthe inner face of-the box (Big. 9). The plunger is now retracted byspring '50, so that the resilient member 49 will contract and recedefromthe box. A still further lateral movement is now imparted. by cam-43' toslide 29 together with matrix 39. This movement will carry the matrixtoward a discharge chute 51, 'oppofor the manufacture of boxes-ofdifferent sizes and shapes.

Figs. 10-13 represent consecutive positions of cam 14, each figureshowingthe cam advanced 90, while lever 13 with roller 13 is alwaysshown in the same position. By

the first partial turn of the cam, ,the lever is advanced to theposition shown in Fig.

At the nextpartial turn, it is twice reciprocated by the duplexundulatiou of the cam groove (Fig. 11). Then the lever is continuouslymoved back into the positibn indi' cated in Figs. 12 and. 13. Thus thelever re cei'ves intermittently three forward movements and a singlebackward movement.
